Saga Natural Language Understanding NLU Framework

how does nlu work

Your NLU solution should be simple to use for all your staff no matter their technological ability, and should be able to integrate with other software you might be using for project management and execution. Natural language includes slang and idioms, not in formal writing but common in everyday conversation. This data can then be used to improve marketing campaigns or product offerings. Saga Natural Language Understanding (NLU) was developed to provide a scalable framework that fills the gaps in existing NLP/NLU technologies. Extract information from highly unstructured content, such as reports, maps, notes, etc. Natural Language Understanding is becoming an essential AI technique leveraged by many enterprises to create competitive advantages across industries and business functions.

Natural language processing works by taking unstructured data and converting it into a structured data format. For example, the suffix -ed on a word, like called, indicates past tense, but it has the same base infinitive (to call) as the present tense verb calling. NLU is branch of natural language processing (NLP), which helps computers understand and interpret human language by breaking down the elemental pieces of speech. While speech recognition captures spoken language in real-time, transcribes it, and returns text, NLU goes beyond recognition to determine a user’s intent. Speech recognition is powered by statistical machine learning methods which add numeric structure to large datasets.

While this ability is useful across the board, it particularly benefits the customer service and IT departments. NLU systems are able to flag the most urgent tickets and recommend solutions thanks to their capacity to understand the context and meaning of the different requests they interact with. The focus of entity recognition is to identify the entities in a message in order to extract the most important information about them. Entity recognition is based on two main types of entities, called numeric entities and named entities. A numeric entity can refer to any type of numerical value, including numbers, currencies, dates, and percentages.

To answer the “when” question, we look for abstracted notions of date, time and, eventually, date-time intervals or duration. In general, NLU’s main goal is to build a document-specific dynamic knowledge graph related to the context of the content/document we are analyzing. The process of testing and deploying Machine Learning and language models is easily done and managed by non-data scientists as it does not require coding. Let’s take an example of how you could lower call center costs and improve customer satisfaction using NLU-based technology. Without a strong relational model, the resulting response isn’t likely to be what the user intends to find. The key aim of any Natural Language Understanding-based tool is to respond appropriately to the input in a way that the user will understand.

Training NLU Models

Optimizing and executing training is not out of reach for most developers and even non-technical users. Recent breakthroughs in AI, emerging in part because of exponential growth in the availability of computing power, make applying these solutions easier, more approachable, and more affordable than ever. The verb that precedes it, swimming, provides additional context to the reader, allowing us to conclude that we are referring to the flow of water in the ocean. The noun it describes, version, denotes multiple iterations of a report, enabling us to determine that we are referring to the most up-to-date status of a file.

Recommendations on Spotify or Netflix, auto-correct and auto-reply, virtual assistants, and automatic email categorization, to name just a few. NLP is concerned with how computers are programmed to process language and facilitate “natural” back-and-forth communication between computers and humans. Natural language understanding is critical because it allows machines to interact with humans in a way that feels natural. Simplilearn’s AI ML Certification is designed after our intensive Bootcamp learning model, so you’ll be ready to apply these skills as soon as you finish the course.

Main differences between NLP and NLU

Models like recurrent neural networks (RNNs), convolutional neural networks (CNNs), and transformers have performed language understanding tasks remarkably. These models can capture contextual information, sequential dependencies, and long-range dependencies in language data. Deep learning approaches excel in handling complex language patterns, but they require substantial computational resources and extensive training data. This includes understanding the meaning of words and sentences, as well as the intent behind them.

This gives your employees the freedom to tell you what they’re happy with — and what they’re not. The NLU tech can analyze this data (no matter how many responses you get) and how does nlu work present it to you in a comprehensive way. With this information, companies can address common issues and identify problems like employee burnout before they become critical.

NLU Components

Chatbots and virtual assistants powered by NLU can understand customer queries, provide relevant information, and assist with problem-solving. By automating common inquiries and providing personalized responses, NLU-driven systems enhance customer satisfaction, reduce response times, and improve customer support experiences. NLU empowers machines to comprehend and interpret human language, bridging the gap between humans and computers regarding effective communication and interaction. It is vital in enabling intelligent systems to process and understand natural language, leading to various applications across diverse industries. Natural language understanding (NLU) technology plays a crucial role in customer experience management. By allowing machines to comprehend human language, NLU enables chatbots and virtual assistants to interact with customers more naturally, providing a seamless and satisfying experience.

There are so many possible use-cases for NLU and NLP and as more advancements are made in this space, we will begin to see an increase of uses across all spaces. Data capture is the process of extracting information from paper or electronic documents and converting it into data for key systems. IVR, or Interactive Voice Response, is a technology that lets inbound callers use pre-recorded messaging and options as well as routing strategies to send calls to a live operator. Using NLU, voice assistants can recognize spoken instructions and take action based on those instructions. For example, a user might say, “Hey Siri, schedule a meeting for 2 pm with John Smith.” The voice assistant would use NLU to understand the command and then access the user’s calendar to schedule the meeting. Similarly, a user could say, “Alexa, send an email to my boss.” Alexa would use NLU to understand the request and then compose and send the email on the user’s behalf.

That means it’ll take you far less time and far less effort to create your language models. It uses many techniques, including sentiment analysis and sarcasm detection, to understand the sentence’s meaning. It will select the request based on his understanding of the underlying meaning.

In such a case, it’s better to use transcreation, which conveys the sentence’s meaning in the targeted language without a word-by-word translation. Natural languages processing is closely related to syntax; it focuses on the structure of languages and grammar aspects. NLP uses tokenization, lemmatization, and stemming methods to extract data from a particular text. Keeping your team satisfied at work isn’t purely altruistic — happy people are 13% more productive than their dissatisfied colleagues. Unhappy support agents will struggle to give your customers the best experience.

Extracting insights from natural language content

These stages or components include morphological analysis, syntactic analysis, semantic analysis, and pragmatic analysis. The final stage is pragmatic analysis, which involves understanding the intention behind the language based on the context in which it’s used. This stage enables the system to grasp the nuances of the language, including sarcasm, humor, and cultural references, which are typically challenging for machines to understand. Once the syntactic structure is understood, the system proceeds to the semantic analysis stage.
